BERNAR a en nni vx, OF EAST CLEVELAND, OHIO, ASSIGNOR ro 'II-IE TRENKAMPSTOVE & MANUFACTURING COMPANY, OF CLEVELAND, GI-IIO, A CORPORATION orOHIO.

To all whom it may concern:

Be it known that I, BERNARD A. GEURINK, a citizen of the United States,and a resident of East Cleveland, county of Cuyahoga, and State of Ohio,have invented a new and use ful Improvement in Gas-l3urners, of whichthe following is a specification, the principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle, so as to distinguish it from other inventions.

My invention provides in general a gas burner for use especially in theheating of ovens of gas-ranges. In particular the invention is designedto provide such a burner which will be of extremely convenient and safeoperation, the invention comprising an improvement on the general formof such burners disclosed in U. S. Patent No. 941,708, granted to me onNovember 30, 1909.

To the accomplishment of these and related ends said invention, then,consists of the means hereinafter fully described, and particularlypointed out in the claims.

The annexed drawing and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawing :-Figure 1 is a broken perspective view of anoven equipped with my improved gas burner; Fig. 2 is a plan view of theburner, and Fig. 3 is a section on the line 3-8 in Fig. 2.

My device consists of two complementary parts A and B which are hereillustrated as separable castings and as including parallel sections,each of which is provided at one end with a mixing chamber a and I)respectively, into which is to be conducted a suitably controllable gassupply and a similarly controllable air supply. Near one end the sectionA is provided with a transverse branch a which extends to the section Bbut does not communicate therewith. The section B is provided with asimilar transverse branch b at the end opposite that at which thesection A is provided with its branch a. The branch I) similarly extendsto, but does not communicate with, the section A. At their ends at whichthey are formed with their mixing chambers, the respective sections areprovided'with two con- Specification of Letters Patent.

tiguously disposed branches (1 and 5 which extend longitudinally of theassembled burner. The burner, when assembled, is disposed above or belowthe oven chamber C, as may be desired, while the oven casing is providedwith a sliding door 0 adapted to close the openings of the contiguouslydisposed branches a and b WVhen it is desired to use the burner,sincethey are non-communicating, the sections must be lightedseparately. This may be done in a most convenient manner by turning onthe gas in both sections and lighting them both at the contiguouslydisposed branches which terminate at a common point. If it is desired tolight only one of the sections, the gas is turned only into suchsection, and itmay thereupon be lighted at the same point as before. Ifsubsequently it is desired to light the second section, this may be doneby simply turning on the gas in such section, for since the two sectionsare formed with branches extending from one to the other such brancheswill serve to conduct the flames from the lighted section to the onewhich it is desired to light, so that the one which was first lighted,in reality forms a pilot light for the section last lighted. It isfinally to be noted that by not having the transverse branchescontiguous to each other, and by providing the sections with separatebranches which terminate at a common point, the two sections may be castindependently of each other and conveniently assembled when desired intoa completed burner. It is, of course, to be understood that I do notlimit such construction to a burner having only two complementarysections, but the burner may be composed of any number of such sectionsdependent upon the amount of heat required.

While I have herein shown the sections of my burner as consisting ofseparable castings, this is obviously a structural detail that may bevaried to suit the convenience of the manufacturer; for it is obviouslya matter of indifference whether such sections be thus cast singly ortogether so as to form an intogral structure of the burner.

Other modes of applying the principle of my invention may be usedinstead of the one explained, change being made as regards the mechanismherein disclosed and particularly pointed out in the claims.

I therefore particularly point out and distinctly claim as myinvention 1. A burner of the character described, comprising a pluralityof non-communicating sections and independent fuel supplies for therespective sections, said sections being provided with branches spacedfrom each other, said branches extending from one section to the body ofthe other, whereby one section may be lighted from another.

2. A burner of the character described, comprising a plurality ofparallel non-communicating sections and independent fuel supplies forthe respective sections, said sections being provided with transversebranches spaced from each other, said branches extending from onesection to the body of the other, whereby one section may be lightedfrom another.

3. A burner of the character described, comprising a plurality ofparallel sections and independent fuel supplies for the respectivesections, said sections being provided with transverse branches neartheir opposite ends respectively, said branches extending from onesection to the body of the other but not communicating with the latter,whereby one section may be lighted from another.

4. A burner of the character described, comprising a plurality ofnon-communicating sections and independent fuel supplies for therespective sections, said sections being provided with branches spacedfrom each other, said branches extending from one section to another,whereby one section may be lighted from another, and said sections beingprovided with portions terminating at a common point.

5. A burner of the character described, comprising a plurality ofparallel non-communicating sections and independent fuel supplies forthe respective sections, said sections being provided with transversebranches spaced from each other, said branches extending from onesection to another, whereby one section may be lighted from another, andsaid sections being further provided with portions terminating at acommon point.

6. A burner of the character described, comprising a plurality ofparallel sections and independent fuel supplies for the respectivesections, said sections being provided with transverse branches neartheir opposite ends respectively, said branches extending from onesection to another but not communicating with the latter, whereby onesection may be lighted from another, said sections being furtherprovided with portions terminating at a common point.

7. A burner of the character described, comprising a plurality ofparallel non-communicating sections and independent fuel supplies forthe respective sections, said sections being provided with transversebranches spaced from each other, said branches extending from onesection to another, whereby one section may be lighted from another, andsaid sections being further provided at one end with branchesterminating at a common point.

8. A burner of the character described, comprising a plurality ofparallel non-communicating sections and independent fuel supplies forthe respective sections, said sections being provided with transversebranches near their opposite ends respectively, said branches extendingfrom one section to another but not communicating with the latter,whereby one section may be lighted from another, and said sections beingfurther provided at one end with longitudinally extending branchesterminating at a common point.
